Fire buckets did not have flat bottoms so they could never be used for other buckety tasks, and were thus always handy in an actual fire.
All of the bucket conveyors crashed on this work floor when their casings were scrapped. Note all of the valves to open the grain flow.
Dirty filters for some equipment hang, awaiting a purpose.
